"The mastery of nature is vainly believed to be an adequate substitute for self mastery"

This quote by Reinhold Niebuhr is a tip that although we might be able to manage and control nature, it is not a substitute for self-mastery. Self-mastery is the capability to manage one's own thoughts, emotions, and actions. It is the ability to be familiar with our own motivations and to make mindful choices that remain in line with our values and objectives. Nature is something that is beyond our control, and while we might be able to manipulate it to some degree, it is not a substitute for the internal work of self-mastery. Self-mastery requires us to be sincere with ourselves, to take obligation for our actions, and to be conscious of our ideas and feelings. It is a process of self-reflection and growth that can assist us to become better versions of ourselves. Eventually, self-mastery is the key to living a life of function and fulfillment.
